Issue with networking

Hello, when I try to enable a e1000 PCI device I receive this error:

make run ARCH=x86_64 NET=on LOG=info

Thank you in advance! This project is very cool!

Which distribution are you using? This probably means you're using an old version of QEMU.

@jiegec thanks for the help. I am running Ubuntu 18.04. Here is the qemu version:

qemu-system-x86_64 --version QEMU emulator version 2.11.1(Debian 1:2.11+dfsg-1ubuntu7.23) Copyright (c) 2003-2017 Fabrice Bellard and the QEMU Project developers

That's too old. You can compile a new one from source code.

Thanks again. I'll download QEMU 5 and go from there.
